--jvm tries to find Java executable system-wide. (#11500)

Fixes `--jvm` option, given to the native image. This was failing on my machine, because when given `--jvm` option, the runner was trying to find the `java` executable from the distribution manager's runtime (on my system located in `~/.local/share/enso/runtime`) and it used the first runtime found. But the first runtime on my system is JDK 17.

The `--jvm` option now tries to:
- Find a JDK from the distribution manager that has the same version as the JDK used for building the engine.
- If there is not an exact version match, it tries to find a runtime from distribution manager that is *newer*.
- If none, fallback to system-wide search
- System-wide search tries to find `java` from `$JAVA_HOME` and from `$PATH`. But this is just a fallback.

# Important Notes
- Added test to Engine CI jobs that pass `--jvm` argument to a native image of engine-runner
- ea3af5ffbc
- `runtime-version-manager` sbt project migrated to a JPMS module
- `engine-runner` now depends on `runtime-version-manager`.
- Removed unnecessary stuff in `runtime-version-manager` dealing with outdated `gu` Graal Updater utility.
- Extracted [GraalVersionManager](1455b025cb/lib/scala/runtime-version-manager/src/main/java/org/enso/runtimeversionmanager/components/GraalVersionManager.java) from [RuntimeVersionManager](d2e8994700/lib/scala/runtime-version-manager/src/main/scala/org/enso/runtimeversionmanager/components/RuntimeVersionManager.scala)
